Assembly type steel structure pier column and cast-in-place concrete pile foundation connection construction method and structure
The invention relates to a fabricated steel structure pier column and cast-in-place concrete pile foundation connection construction method and structure. Existing connection construction needs bearing platform transition, so that the excavation work amount is large, the use amount of construction materials is large, and the number of construction procedures is large. According to the method, vertical perforated steel plates and annular penetrating steel bars are arranged on the inner side of the bottom of the steel structure pier column; vertical steel bars are bound to the peripheral sides of the penetrating steel bars, and stirrups are bound to the outer sides of the exposed parts of the lower portions of the vertical steel bars; a pile foundation reinforcement cage of the concrete pile foundation is lowered, the steel structure pier column is hoisted above the pile foundation reinforcement cage, and the vertical steel bars and the pile foundation reinforcement cage are bound into a whole; and the top of the pile top section concrete is poured above the bottom of the steel structure pier column. The arrangement of a bearing platform is omitted, the connecting structure is simplified, the technological procedures in the construction process are effectively reduced, the construction method is convenient and fast, the construction efficiency is high, consumption of materials such as concrete, steel and steel bars is effectively reduced, and the economical advantage is obvious.
本发明涉及一种装配式钢结构墩柱与现浇混凝土桩基连接施工方法及构造。现有连接施工需要承台过渡，导致开挖作业量大、施工材料用量大、施工工序较多。本方法于钢结构墩柱底部内侧布设竖向的开孔钢板及环向的贯穿钢筋；于贯穿钢筋外周侧绑扎竖向钢筋，并在竖向钢筋下部外露部分外侧绑扎箍筋；下放混凝土桩基的桩基钢筋笼，吊装钢结构墩柱于桩基钢筋笼上方，并将竖向钢筋与桩基钢筋笼绑扎为一体；立模浇筑桩基混凝土，桩顶段混凝土顶部浇至钢结构墩柱底部外以上。本发明取消了承台的设置，简化了连接构造，有效减少了施工过程中的工艺工序，施工方法便捷，施工效率高，有效降低混凝土、钢材、钢筋等材料消耗，经济性优势明显。
